ABSTRACT:
A pair of quantized duty ratio proportional-integral-differential (PID) converters are coupled to provide power sharing to a load. One of the converters is a master and the other is a slave, and a PID controller is coupled to both of the converters. The PID controller also supplies two digital offset signals to the converters during normal operation, which insures load sharing by control of the duty ratio of the converters. If one of the converters fails, a sensor control unit switches control to the other unit and the digital offset signal goes to zero.
